[T3] I'm a bit confused as to why unplugging this IAD temp sensor clears things up.

Using it as a placeholder is fine. You will never be able to see any difference 
in driving performance on this car between a functioning and non-functioning 
vac can. That's true of all the FI cars except for the '72s. On '72s things get 
very bad if the retard is broken. Unfortunately, only the retard side of those 
ever breaks.

Check yours with a small hose. If it's truly bad, I have NOS ones, not cheap, 
but half the price of the online place I saw last night.
